+//! \brief Ensures that a range, composed of a base and a size, does not
+//!     overflow the pointer type of the process it describes a range in.
+//!
+//! This class checks bases of type `win_vm_address_t` and sizes of type

If you rename these to WinVMAddress and WinVMSize, you won’t need to backtick
them, because Doxygen will automatically link to their definitions. If you don’t
rename them, Doxygen won’t auto-link because they don’t have at least one
uppercase letter, so you’ll need to write ::win_vm_address_t instead of
`win_vm_address_t` to get proper linking. Backticks are for system types that we
don’t provide the docs for and can’t link to.

Done.

+//! `mach_vm_size_t` against a process whose pointer type is either 32 or 64

[Mark Mentovai, 2015/05/01 19:05:31]

This one shouldn’t talk about Mach.

[scottmg, 2015/05/01 19:46:32]

Done.

+//! bits wide.
+//!
+//! Aside from varying the overall range on the basis of a process' pointer type
+//! width, this class functions very similarly to CheckedRange.
